Sunset tonight -- if it's clear-- will be special in Manhattan.
The so-called "Manhattanhenge" will occur this evening, "when the setting sun aligns precisely with the Manhattan street grid, creating a radiant glow of light across Manhattan's brick and steel canyons," according to Neil deGrasse Tyson of the American Museum of Natural History and host of the TV show Cosmos.
It illuminates "both the north and south sides of every cross street of the borough's grid," he said, adding that "Manhattanhenge may just be a unique urban phenomenon in the world, if not the universe."
The dates can vary year to year, but it usually occurs around May 28 and again around July 12, according to WeatherBug.
The best locations are as far east in Manhattan as possible, "but make sure that when you look west, you can still see New Jersey," WeatherBug' reports. "Clear cross streets include 14th, 23rd, 34th, 42nd, 57th and several adjacent streets."
NBC News says to "watch for the #manhattanhenge and #manhattanhenge2014 postings to Twitter and Instagram."
Peak time tonight is about 8:16 p.m. As of mid-morning it is clear in New York, reports WLKY-TV, and hopefully it will be that way for Manhattanhenge tonight.
After tonight, the other summer date to see this sunset in July 12, WLKY reports.
Tyson dubbed it Manhattanhenge as an homage to Stonehenge, in the Salisbury Plain of England. For Stonehenge, the special day is the summer solstice, when the sun rises in perfect alignment with several of the stones, signaling the change of season.
